Wraps Open-Meteo's free weather APIs with eight MCP tools covering geocoding, 16-day forecasts, ERA5 historical climate back to 1940, marine conditions, CAMS air quality, and Copernicus terrain elevation. You geocode a place name to coordinates, then pull hourly or daily variables like temperature, precipitation, wind, wave height, or PM2.5. Historical queries over large date ranges spill to DataCanvas with SQL query tools for analysis. Supports both stdio and streamable HTTP transports, with a public hosted instance at open-meteo.caseyjhand.com. Useful when you need global weather context without API keys, or want to compare forecast models against reanalysis data in a single schema.
